CRITICAL FIX: Handle grep failures with set -eo pipefail in scanner installation

Browse Source 
FIXED:
- Added '|| true' to all grep commands that filter installation output
- ClamAV installation: Fixed grep exit code issue on yum/apt-get output
- Maldet installation: Fixed signature update grep failure handling
- ImunifyAV installation: Fixed deployment script grep and update grep failures
- Changed imunify update from pipe-to-grep-or-retry to proper if-statement check

BEHAVIOR CHANGE:
- Installation continues even if output patterns don't match expected strings
- Signature updates now use if-statement with grep -q instead of bare pipes
- Better status reporting: shows 'unclear' instead of error when status unknown

ROOT CAUSE:
With 'set -eo pipefail' enabled, grep commands that return 1 (no match) cause
the entire pipeline to fail. This was causing the installation to exit with code 1
even though the software was actually installing successfully.

EXAMPLE:
Before: yum output 'Complete!' → grep looks for 'Installing' → grep returns 1 → exit
After: yum output 'Complete!' → grep returns 1 → handled with '|| true' → continue
